Terminology for Perron root

Opened this issue · 0 comments

Things are a little murky right now:

  • ReciprocalPolynomialBoundedList restricts to Perron root. Is this the best idea? Probably.
  • Usage, from LT2010b: "Perron root" is the root itself (signed), "Perron number" is the absolute value.
  • PerronRoot doesn't quite do that, since it returns the largest root (in magnitude), even if the polynomial is not Perron. Would it be better to call it LargestRoot or MaximalRoot?
